I think that has a big effect with these wide tires.

I am a very strict adherent to hist tire pressure ideas.

I set up for 41% weight on the front and 59% weight on the back. That is a pretty big variation in pressure.

E.x. I said I have 26s and 32s on my two bikes respectively. Based on 41/59 I run these pressures, and I'm about 175lbs.

26c: 62psi front, 88psi rear
32c: 45psi front, 65psi rear

It works really well. Get the weight distribution right and you're running lower pressures without anything getting squishy or sloppy. It's seem absolutely nuts to me at this point to think I used to run equal pressure front & rear. That almost always leads to a really harsh ride on the front of the bike and a squishy rear tire.

Weight distribution is dynamic though - so you're only getting it "right" when riding in a straight line on flat ground and not braking or accelerating....no?
